Internship Hvac Estimator Jobs in Gilbert, AZ (NOW HIRING)

Job Description | Phoenix, Arizona | Full-Time | On-Site

Compensation

$85,000-$105,000 base salary, depending on experience, commercial estimating depth, and software/AI capability.

Bonus Opportunity

Performance-based bonus tied to bid throughput, estimate quality, awarded work, and handoff discipline.

Reporting Focus

Commercial HVAC estimating, preconstruction support, process improvement, and bid workflow ownership.

Target Output

Support a pipeline averaging 2-3 estimates per day across budgets, change orders, repeat scopes, and full bid packages, depending on complexity.

We are seeking a highly capable Commercial HVAC Estimator / Preconstruction Specialist to support a growing pipeline of commercial work. This role is responsible for building accurate, competitive, and executable estimates; coordinating vendor and subcontractor pricing; reviewing plans, specifications, and addenda; and improving the speed, consistency, and quality of the estimating process. The ideal candidate is technically strong, process-driven, comfortable using AI and digital tools to refine workflow, and capable of supporting a high-output bid environment without sacrificing accuracy, margin discipline, or clean turnover to operations.

• Review project plans, specifications, blueprints, schedules, and addenda to develop accurate cost estimates for commercial HVAC systems and related scopes.
• Perform takeoffs and pricing for equipment, ductwork, sheet metal, controls coordination, TAB coordination, startup/commissioning support, permits, crane/lift needs, and subcontractor scope where applicable.
• Analyze labor, material, equipment, subcontractor, and general conditions costs to build competitive bids that align with scope and margin expectations.
• Coordinate with vendors, subcontractors, project managers, sales, and field leaders to validate constructability, pricing, lead times, scope gaps, and execution feasibility.
• Prepare proposals, clarifications, exclusions, alternates, and value-engineering options with clear scope language and professional presentation.
• Use AI and digital estimating tools to accelerate takeoffs, troubleshoot scope questions, compare bid scenarios, improve proposal refinement, and reduce bid cycle time.
• Continuously refine templates, pricing libraries, assemblies, workflow standards, and estimating SOPs to improve consistency, speed, and accuracy.
• Participate in bid review and turnover meetings to document assumptions, exclusions, labor strategy, risk items, and handoff requirements for operations.
• Conduct site walks or field verification when needed to assess project conditions and improve pricing confidence.
• Stay current on HVAC systems, software tools, manufacturer updates, pricing trends, local code requirements, and market conditions.

• Support a bid pipeline averaging 2-3 estimates per day across conceptual budgets, repeat scopes, change orders, design-build pricing, and full bid packages, depending on complexity.
• Maintain disciplined turnaround times while preserving estimate accuracy, scope completeness, and gross margin alignment.
• Help improve throughput by using AI, templates, standardized workflows, and strong vendor/subcontractor coordination.
• Contribute to better estimating outcomes through cleaner scope review, fewer missed items, and stronger turnover to operations.
• Operate with urgency, ownership, and sound commercial judgment in a fast-paced bid environment.

• Proven experience as an HVAC estimator in commercial construction, mechanical contracting, or related preconstruction roles.
• Strong understanding of commercial HVAC systems, installation methods, field sequencing, and cost drivers.
• Ability to read and interpret blueprints, mechanical plans, specifications, schedules, and construction documents with minimal supervision.
• Experience with estimating software and takeoff tools such as FastDUCT, QuickPen, BidTracer, Bluebeam, or comparable platforms.
• Comfort using AI tools such as ChatGPT or similar platforms to improve workflow, summarize scope, troubleshoot estimating questions, and support faster decision-making.
• Strong Excel, Word, Outlook, and digital organization skills, with clear communication and strong attention to detail.
• Working knowledge of local codes, industry standards, and safety requirements that impact commercial HVAC pricing and installation.
• HVAC-related certifications, field experience, or formal training in mechanical systems, construction management, or engineering are preferred.
